fixed bug where cannot create new story
tagging_by_hand coded but with fatal defects
tags can be CRUD, clickable tag cloud appears at top of index page, tags show in story lists, reduced size of textareas for forms, upped version to 6.1.  Tags are not clickable anywhere except in the cloud at the top of the index page.  Tags are not sized according to frequency.
